Gizmodo has put together a handy graph that pits the G1, feature for feature, against some of its contemporaries. As you can see here, the T-Mobile G1 is the least expensive of the bunch, ringing in at a mere $179 with a two-year contract. The size of its HVGA touchscreen display is only second to the iPhone, but the Android gPhone has the added advantage of a full QWERTY keyboard to boot. Talk time on the battery is on par with the rest, and the camera seems to be about the same as the other HTC phones (Tilt, Touch Pro). The two most notable deficits on the T-Mobile G1, however, are the lack of Exchange support and the lack of desktop synchronization.
